CORNER-DEAD HOLDER.

aooaeee.

T 0 all whom it may concern:

Be it known that we, EDWARD MIDDLETON and CHAnLns PORTER, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in CornerBead Holders; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw ings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in holders for corner beads used as a reinforce ment and support at the vertical corners of rooms and the like in applying plaster to the intersecting walls thereof. Said holder is adapted to grip and support the corner bead while it is being applied to the corner and is provided with means for adjusting the bead so that it will stand in a true vertical line.

The invention consists of the matters hereinafter described and more particularly pointed out in the appended claims.

Our improved bead holder comprises two bars, preferably made of wood, each having a longitudinal plane face adapted for engagement with a like face of the other bar, and the two bars being hinged together along one lateral marginal edge of said faces by means of hinges, some of which are provided with springs adapted to normally hold the said faces of said bars in contact. The said longitudinal faces of the bars near their free marginal edges are provided with oppositely disposed longitudinal grooves adapted to receive the flanges of the corner head so that the said faces of the bars are adapted to clamp against and hold the corner bead throughout its length securely gripped between them. For convenience in handling, the bead holder is preferably made in two parts, a base member and an upper member, which are adapted to be connected together end to end. In practice, two or more upper members are provided for each base member in order to accommodate the corner beads of various lengths adapted for rooms with ceilings of different heights.

Referring now to that embodiment of our invention, illustrated in the drawings, and particularly to Figs. 1 to 5, inchilsive, A indicates the base member of the bead holder and B the upper member. Each of said members are generally of like construction and comprise bars a, a, having longitudinal, plane faces C, C, along one marginal edge of which said bars are hinged together, and near the opposite marginal edge of which each is provided with a longitudinal. groove 0 adapted to receive a flange of the corner bead. D indicates hinges by means of which the bars a a are hinged together and E spring hinges which tend to hold said bars with the longitudinal faces C, C clamped together. For convenience in separating the free margins of the faces (3, C to receive the corner bead, each of the bars a of the base member A is provided preferably near the spring hinge with short curved thumb or finger arms 6 which are adapted to be grasped by the thumb and fingers of one hand and pressed toward each other thus swinging the coaeting faces of the bars apart on their hinged connection when the corner bead may be inserted between them.

The base member of the device is provided at its lower end with vertical supporting pins F, F, mounted in apertured lugs f, in which they are held rigid by means of set-screws f. Said pins may be moved up or down in the apertures of their respective lugs to accommodate variations of level in the floor at the corner where the corner bead is to be applied. At a point at a convenient level above the lower end of the base member of the bead holder, said base member is provided with two horizontal levels G, G arranged in vertical planes at an angle to each other and a vertical level 9. By observation of said levels the bead holder may be brought to a position, so that the bead will be held in true vertical position.

The upper and base members of the device are removably connected together by the following mechanism: At the upper end of the base member the bars a, a, are each provided with extension plates H, H, each covering all of the faces of the associated bar a except the faces C thereof. Located within the space inclosed by said plates H, H, are reduced extensions J, J, of the bars a, a, of the base member A which are adapted for engagement within longitudinal recesses J, J, formed at the lower ends of the bars a a of the upper member B of the device. As shown herein, said recesses are formed by providing longitudinal grooves in the op posite outer faces of the upper bars a, a, and inclosing said grooves by means of lates j. In connecting the two members of the bead holder together, the lower end of the upper member is inserted in the space inclosed by the plates H, H, the extensions J, J, of the base member at the same time engaging within the longitudinal recesses J, J of the upper member. By this construction, each bar a of the upper member is rigidly connected to and becomes a longitudinal extension of the corresponding bar a of the base member of the bead holder so as to swing with it on its hinges when the bars of the lower member are swung apart to receive the corner bead.

In Figs. 7 and S, inclusive, a modified form of the device is shown. In this case a indicates the bars which each have a cross-section substantially in the form of right angled triangles (see Fig. 8) the. hypotenuse of which lies in the longitudinal plane face of the bar adapted for clamping engagement with the bead. The cross-sec tion of the bars of the bead holder in this case, makes it possible to sight from the hinged marginal edges of the bar along each of the walls which come together at the corner where the bead is being applied, thus making it more convenient to adjust the position of the bead. In this construction of the device the upper and lower members B, A, of the bead holder are hinged together at their adjacent ends instead of being detachably connected as in the first case. K indicates the hinge by which the upper and lower members are connected together, the leaves of said hinge being secured to two of the corresponding outer longitudinal faces of said upper and lower members. On each of the other outer faces of the upper member B are provided pivotal latch-bars L, which have notches in their lower ends adapted for engagement with pins or screws Z secured to the corresponding outer faces of the bars of the lower member A. The abutting ends A, r of the two members of the bead holder (see Fig. 7) are provided with pins and recesses adapted for engage ment to secure a true vertical alinement of the corresponding bars a of the two members. As shown in the drawings, one of the bars a of the upper member is provided with a pin M adapted for engagement within .a recess m in the corresponding bar a of the base member, while the opposite bar of the base member is provided with a pin I adapted for engagement in a recess a in the corresponding bar a of the upper member. By this construction the upper member may be swung on the hinge K into alinement with the base-member, the said pins engaging in their associated recesses as the ends A A of the member abut against each other. The latch-bars L are then swung on their pivotal connections to bring their notches into engagement with the associated pins Z. This locks the corresponding bars a of the two members rigidly together end to end so that the bars of the upper member become rigid extensions of the bars of the base member.

In Fig. 9 we have shown another manner of supporting the bead holder to be used instead of the adjustable supporting pins F heretofore described. In this case A indi cates the upper member of the bead holder and P, P, indicate supporting hooks secured to the upper end thereof by means of which the device is supported from the usual molding located near to and parallel with the ceiling. As this molding is usually placed with care and is generally located in a horizontal plane no vertical adjustment of the said supporting hooks is required.

The way in which our improved bead holder is to be used will be apparent from the above description. the bead holder is shown supporting a corner bead in position for attachment to a corner of two intersecting walls. B. indi, cates the bead which has longitudinatl flanges r 1' together forming the ball of the bead and which the longitudinal grooves 0 0 In Figs. 1 and in the gripping faces C C of the bead holder bars are adapted to engage. Q indicates an attachment; connected to the bead and having a plurality of lateral extensions Q adapted to be secured to the two walls near their intersection. With the two members of the bead holding device in extended relation, the gripping bars are swung apart, the bead is inserted and the bars are clamped upon the bead in the manner above described. The bead is then raised into upright position against the corner and by manipulation of the bead holder is brought into true vertical position. It is then secured by nails or otherwise to the intersecting walls in a familiar manner.

While in describing our invention we have referred to certain details of mechanical construction, it is to be understood that our invention is not limited thereby except as pointed out in the appended claims.
